Node access table can be left in inconsistent state if node_access_needs_rebuild is not set.

Problem/Motivation

node_access_rebuild() clears the node access table, then rebuilds it. We had an issue were node_access_rebuild() was called during directly during a deploy script, and failed to complete due to a memory exhausted error, leaving the node access table in an inconsistent/incorrect state and causing access denied on most pages.

Since node_access_needs_rebuild was not set to TRUE prior to calling node_access_rebuild(), there was no indication that the node access table was not rebuilt correctly.

While best practice is probably to call node_access_needs_rebuild(TRUE) prior to / instead of calling node_access_rebuild() directly, it makes sense to set node_access_needs_rebuild explicitly once the operation is started. The flag is cleared automatically after successful completion.

Proposed resolution

Once node_access_rebuild() clears the node_access table, force the node_access_needs_rebuild flag to TRUE. This way, if the function fails (long-running/time- and memory-consuming, so not unlikely to happen), it is clear that a rebuild is still required.
